- Application filed June 30, 1909. Serial No. 505,295.

To all whom it may concern:

Be it known that I, GEORGE W. RATHFON,

- citizen of the United States, residing at marked to give a fanciful appearance to the same.

An object of this invention is to provide an attachmentto a practical molding machine whereby the plastic block which is fed upon the mold to the cutter is brought into engagement with the improved device to indent the surfaces thereof in order to form fanciful configurations upon the same.

The invention has for :another object the provision of an improved mechanism which is adaptable to a mold for engaging the plastic blocks as they are fed to the molds and which operates in conjunction with the feeding mechanism of the mold.

The invention further contemplates a marker of this character which is adaptable to molds of various types and'which may be I detached from the same when not desired.

For a full understanding of the inyention reference isto be had to the followlng description and accompanying drawings, in

which Figure 1 is a side elevation of the carrier of the molding machine with the improved apparatus applied thereto, and discloses a plastic block secured to the same. Fig. 2

is a section on the line 2-2 of Fig. 1. Fig. 3 is a fragmentary vrewshowmg the transverse section through the marker and a longitudinalsection through the carrier and aengaged over the face of a carrier located adjacent the lip 11. The carrier comprises the studs 13 which are disposed in pairs and are spaced apart from one another in the upper endsof which are journaled trans verse shafts l4- and 15 upon which enlarged rollers 16 and 17 are disposed. An endless belt 18 is momited over the rollers 16 and 14 and is supported atthe upper end of the carrier upon a plurality of reduced transverse rollers 19 which are disposed in spaced relation beneath the under surface of the endless belt 18 and journalcd attheir opposite ends in the side boards 20 longitudinally positioned between the standards 13.

and at the opposite sides of the carrier. The endless belt 18 is thereby retained in a sub stantial y horizontal plane upon the upper side of the carrier in order to form a smooth ilQllfaCG for the reception of the plasticblock suitable table21, or the like is positioned to which the plastic block 12 is. fed in order to be cut into bricks of the desired-size.

The marker which comprises the essential part of this application is formed of a ver tical frame which is secured to the sideboards 20 and transversely positioned ccntrally of the carrier. The frame comprises a shank 22 which is engaged against the outer face of one of the sideboards 20 and which is provided with longitudinal and central slots 23 through which are extended clamping bolts 24: carried by the sideboard 20 inorder to admit of the verticaladjustment of the shank 22. The upper end of the shank 22 is bent outwardly at substantially right angles to form a lower horizontal arm 25 which terminates in an offset portion 26 which is vertically disposed and which is curved inwardly at its upper end to form an upper horizontal arm 27, the upper horizontal arm 27 being extended the entire width of the carrier. The opposite end of the arm 27 is supported upon a standard '2 which is flanged atits upper extremity as at 29 to engage beneath the outer end of the arm 27 and to admit of the positioning of a rivet or bolt 30 in brder to secure the same rigidly in position. The standard 5 cxtends downwardly and engages against the opposite side board 20 upon the outer face thereof where it is secured thereto by mean of clamping bolts 31 which are engaged through longitudinal and central slots formed'in'th'e lower end of the standard 28 At the opposite end 0 the carrier a 42 and upon which is positioned a belt 44 the clamping bolts 31 being carried by the side board 20. Disposed beneath the upper horizontal arm is an L-brace 32 which is formed of a metallic strip turned over at its upper end as at 33 to engage against the er face of the horizontal arm 27 and to accommodate the positioning of rivets 34 or the like therethrough for retaining the L- brace 32 in position. The lower end of the L,- brace is extended outwardlyasat 35 at its lower end toform a journal and is retained rigidly in such position by a downturned portion-36 which is engaged against the inner face of the offset portion 26 and secured thereto by rivets 27 or the like. 7

Transversely mounted in the frame and "journaled at its opposite ends in the standard'28"?a;1'1d lower end of the L-brace 32 is a shaft. 38, 'one extremity of which extends beyond theLbrace 32 and passes outwardly 7 through the offset portion 26 where it is terminated in a bracket 39 which is carried .upon the side of the offset portion 26. The

Y shaft 38 is provided with a pulley 40 which is keyed thereto between the offset portion 56 and the bracket 39 and supports a belt 41 carried downwardly to engage about-a pulley 42 located upon one side of the carrier upon the shaft 14. The shaft 14 carries a second pulley 43 outwardly of the pulley which is connected to a sourceof power in order to drive a carrier and marking mechanism. Intermediately positioned between the L-brace 32 and the standard 28 is a roller 45 which extends the entire width of the carrier and which is formed of a cylindrical wooden body 46 covered by a casing of cylindrical wooden body-portion 46. The

roller 45is rigidly =keyedto the shaft 38 andadapted for..rotatiorhqtherewith.v A stubshaft 49 is carried-. bythe frame which 1s ve cally disposed between the lower end of the L- brace 32 andthe lower horizontal arm 25,th'e'*"stub-shaft 49 being provided with a beveled gear 50 at the upper end thereof and meshes "with a second beveled gear 51 carried upon the'shaft 38 adjacent theibrace 32 for the purpose of imparting rota-.

49. The stub-shaft 49 carries a roller 52 which is of similar formation to.the-";roll er 45 and'wh'ich is also provided. with a pl rali ty of pins 53 to cooperate with the pins.

' 48 Iof the rolle1n-45 'to mark the plastic body 12 which is drawn from the mold 1O "moved across'therarrier';

L The operation of the marker is as followsz-W hen the plastic body 12 is emitted from the mold'lO the carrier is set in motion through the medium of the belt 44. and pul ley 43, the-pulley 43 revolving the shaft 14 which rotates the large roller 16 and moves the endless belt 18, whereby the large roll 17 and the shaft 15 are revolved. This carries the endless belt over the reduced transverse rollers 19 which support the plastic body 12 alnd carries the same evenly over the upper face of the carrier. Simultaneously with this'opei'ation the pulley 421$ rotated to cause the operation of the belt'41 and consequently the rotation of the pulley 40."

This motion causes the-"revolving of the shaft 38 to carry the roller 45 about therewith and to'also rotate the stub-shaft 49 and roller 52. '1

It will be, noted'from the drawings that the; rollers 45 and 52 are 'o'fiik'e' diameters and also that the beveled gears 50 and 51 are of like size, thereby producing the'registering of thetworrollers' across the topand side of the plastic body 12; as it is fed forwardly over the carrier. The pins 48 and 53 are disposed upon'therolleis'45' and 52in any is claimed as new is:-- tion from the shaft 38 to. the stub-shaft adapted relation in order to engage in the faces of the'plastic block 12 andio form indentations within the same. The clamping bolts 24 and 31 .a'dmitjof the raising of the entire frame which supports the markingmechanism in order to accommodate plastic bodies, of various thicknesses according to the form and sizei-of the mold to which the marker is applied. f; The spa ,ng of he rollers 45 from the upper leg of the'c onveyer 18 prevents the upward movement of the plastic block 12 upon the conveyer. The" roller 52 in conjunction with the member 28 at the side of the transverse frame prevents the spreading and lateral movement of the plastic block during its passage through the marker. This arrangement of the frame and the rollers therein, provides a j housing which completely inclo'sesfihe plastic block during its passage througlithe markerand prevents the deformation of the blockhnder the pressure. v t

The teeth which are carried in the peripheries of the rollers 45 and 52 serve the double function of not only indenting the surfaces of the block 12 but also assisting in the feeding of the block through'the'inarker;'

Having thus described the invention what .1.
